ARIN will place an equivalent of a /16 of IPv4 address space in a reserve for Critical Infrastructure, as defined in section 4.4. If at the end of the policy term there is unused address space remaining in this pool, ARIN staff is authorized to utilize this space in a manner consistent with community expectations.

Change Section 4.4 Paragraph 2 to:

ARIN will place an equivalent of a /15 of IPv4 address space in a reserve for Critical Infrastructure, as defined in section 4.4.

Rationale:

Additional critical infrastructure is being added to the Internet and in a number greater than anticipated when this proposal was written and adopted.

The original CI pool was created to serve new IX and new CI requirements. The pending need is estimated in the 600 new gTLD range. With a /24 assignment from the existing boundary and the likelihood of some sharing platforms, assigning a /15 would seem prudent. I have removed the limited term. I have proposed implementation to occur at the point where there is only an equivalent of a /8 available overall. The process for completing the gTLD additions still has some time to play out, but it is likely we will have exhausted by the time that the process does fully play out.
